Abstract
An acoustic signal reproducing apparatus for reproducing acoustic signals through headphone devices is disclosed. The left channel and right channel acoustic signals are provided by a device for processing the transmission characteristics with constant transmission characteristics representing the location of an imaginary sound source relative to both of the listener's ears. The left channel and right channel acoustic signals, processed in this manner by the device for processing the transmission characteristics, are provided by an acoustic signal processing device with a level difference and a time difference consistent with changes in orientation of the user's head. In this manner, optimum binaural reproduction with respect to the imaginary sound source may be achieved.
